US Patent 7712258 Suspension and sill system for sliding members

A panel or door suspension system used to hang sliding panels or doors. The panel members are hung by an upper bearing assembly with bearings on each side of the longitudinal axis of the panel thereby allowing the weight of the door to bear wholly on the upper bearings and to act centrally and downwardly between the bearings thereby preventing a moment on the bearings. A wedge member attached to the upper portion of the panel allows for vertical adjustment of the panel relative to the bearings and the door frame. A sill assembly beneath the panel allows for stable sliding operation of the panel member, provides for debris drainage and facilitates servicing of the members comprising the sill assembly.
